The recognition of finest color differences on surfaces of all kinds is the strength of the CROMLAVIEW® CR100 color sensor. Due to an optical fiber connection the sensor can be adapted to a large number of applications. Thus, the size of the measuring spot and the working distance are variable. Through a sophisticated control concept the sensor can be comfortably be parameterized via buttons. For more complex tasks a PC tool is provided which visualizes all settings and manages the 350 colors that can be stored in the sensor and be exported in a CSV file if required. With a size of (50 × 50 × 21) mm³ the sensor that has been equipped with a powerful LED is very compact. The integrated stabilization channel technology CROMLASTAB® ensures reliable operation during the whole life cycle and protects it from temperature drift as well.

The functional principle of the CR100 is based on the three range procedure. The measuring light is assessed with the tristimulus value functions and assigned to the three wave length ranges red, green and blue. Through the assessment with these tristimulus value functions the sensor is able to perceive colors similar to the human eye. The sensor contains an own white light source clocked with a frequency of up to 10 kHz. Sampling takes place in both, the light and the dark phase. Additive ambient light cannot change the difference between the light and dark phase, so that the sensor is independent from ambient light.
